Exercise 4-9 Equivalent Units and Cost per Equivalent Unit-Weighted-Average Method [L04-2, L04-3] Pureform, Inc., uses the weighted average method in its process costing system. It manufactures a product that passes through two departments. Data for a recent month for the first department follow. Units Materials Labor Overhead Work in process 86,000 $ 70,200 $ 39,600 $ 53,000 inventory, beginning Units started in process 814,000 Units transferred out 820,000 Work in process 80,000 inventory, ending Cost added during the $928,000 $488,640 $654,160 month The beginning work in process inventory was 80% complete with respect to materials and 65% complete with respect to labor and overhead. The ending work in process inventory was 60% complete with respect to materials and 40% complete with respect to labor and overhead.
